Update router-bridge@0.6.4+v2.9.3

[sachindshinde]

Updates to latest router-bridge and federation version. This federation version:

• Fixes a query planning bug where operation variables for a subgraph query wouldn't match what's used in that query.
• Fixes a query planning bug where directives applied to __typename may be omitted in the subgraph query.
• Fixes a query planning inefficiency where some redundant subgraph queries were not removed.
• Fixes a query planning inefficiency where some redundant inline fragments in @key/@requires selection sets were not optimized away.
• Fixes a query planning inefficiency where unnecessary subgraph jumps were being added when using @context/@fromContext.
